Inthe center ormiddleof each of these wheels I trim a smallmgroove, as seenat P, Fig. 2.

I This standard is esigned to move the cloth along about one-fourth of an inchsquare and about an inch high. I now place in this standard one end of the SLIRfL U. The other end of the shaft U goes into the T-shaped standard tit-.6, Fig. 9'. This shaft U passes transversely over away,-as seen at W,'Fig. 1. The object in havingthese shafts so closetogetheris, that when the shaft Uis slightly turned it. will press down on E and cause the cog-wheels K and O to mesh closer together and press hard on the needle, thereby holding it firmly while the cloth is pulled oil from it. Attached to this transverse shaft U is the lever X, by which is produced its-rocking motion. On this holder 2, Fig. .1. This needle-holdermay be of any convenient size and form. The size and shape represented inthe cirawingsanswer a good purpose. It is slipped onto the transverse shaft U, and held then by a screw,'a, Fig. 2.. This needle-holder canvhe moved backward or forward on the transverse shaft Utoaccnmtnodate different-lengthed needles. This machine can-hefastened to a table or stand, or any convenient place, by being screwed per man'en-tl-y there'tm'or'can be fastened by a common thumb-screw. e

' To operate my lnachine' I place a common needle, already threaded, in the grooves of the :cog-wheels, so that the extreme point of the needle shall come; exactly on a line with the centersof the wheels L and M.- I then place the needle-holder so that it bears gently against the eye of the needle.- Ithen enter the cloth to-he sewedbetween the wheels L and M and ,turn the crank. This. operation draws the cloth into the wheels, crimps it, and while crimped throws-it onto the needle, forming stitches very'rapidly. When the needle is as full asit will hear I press gently on the lever 21. This movesthe needle-holder awayfrom wheels upon the needle and holds it firmly, so that I can pull off the. cloth in almost an instant of time, thus very greatly facilitating the WOIIL. I now reverse the pressure on the place, and I proceed as before.

1 do not" claim that this machine will sew thick cloth orthat it is at all adapted to tailoring purposes; but that for light and thin cloth it-is useful. Especially is it useful lll'-Illlland so close as to require it to be cut partly shaft also is placed the adjustable .needlethe needle, and at the same time presses the lever X when the needle-holder resumes its Hing up dress-shirts, shirring bonnets, The cembination of the crimping-wheels L gatl1ering,f and for doing a large portion of and M with the adjustable needle-holder z, ordinary family sewing. and transverse shaft U, substantially as herein I do not elai; the use of crimping-wheels in described and for the purposes herein setforth. sewing-machine's, the samehaving been already used in the machines of Benjamin W.
